I think its because they're all accomplished designers. So instead of really wanting it like previous contestants they have a "Why am I here? I'm too good for this" type of attitude.

I see what you're saying. That's an interesting point; however, in earlier seasons, even established designers (Kara Saun, for example) did not seem as fussy or preening, especially not this early in the competition. Or maybe I'm misremembering? Also, you'd think these people would know what they're signing up for.

the preview clip where they showed Tim Gunn sending someone packing (did that happen in the road to the runway episode before this one? or is that yet to come?)

Not sure, DT!

Aiiieee! Heidi's outfit makes her look like a bad 80s bar whore.
